Moonbeam is no longer an Ethereum-compatible smart contract chain on Polkadot. On 3 July 2026 the project said it would move its GLMR token to Base, an Ethereum layer-2 network. Every parachain GLMR became one ERC-20 GLMR on Base, and the bridging deadline was 31 July 2026. GLMR is now described as the native token of the "Moonbeam Protocol", a pre-launch settlement network for AI agents. The old jobs of paying gas and staking with collators ended along with the parachain.
What happened, in order
3 July 2026: the strategic update
In its announcement "Moonbeam Strategic Update: Moonbeam Network Relaunches on Base", Moonbeam said that "All existing GLMR holders must bridge their tokens from the Moonbeam parachain to Base before July 31, 2026." Its main points:
- Ratio: 1:1. "Every GLMR you hold today becomes one Base ERC-20 GLMR."
- Self-custody holders had to bridge through the migrator portal at migrate.portal.moonbeam.network. Before bridging, they first had to withdraw anything deployed in Moonbeam DeFi, such as liquidity positions, lending markets and staking contracts.
- Holders on custodial platforms were told that no action was needed and that the platform would handle the migration.
- Collators and infrastructure providers were told that "No immediate action is required" and that guidance would come to them directly.
- The warning: "Once the chain winds down, funds left in on-chain protocols may become inaccessible."
- The reason given: "we believe AI-native on-chain coordination represents a significant long-term opportunity."
The post gave the GLMR contract on Base as 0xb3846fd356c2149ee8d30b0449088dc74e265459. It said nothing about total supply, minting, burning or other changes to tokenomics.
The post also contradicts itself. The main text sets a firm 31 July deadline, but its FAQ says the deadline is "the end of the transition period" and that guidance on doing nothing would come later.
7 July 2026: Moonriver follows
Moonriver, Moonbeam's sister network on Kusama, announced the same move for MOVR: 1:1 to an ERC-20 on Base, no fee, and a deadline of 31 July 2026.
31 July – 1 August 2026: bridge closed, chain in maintenance
According to the infrastructure provider Tatum, the Moonbeam Foundation "closed the bridge on July 31, 2026", and "The Polkadot parachain entered maintenance on August 1 and no longer accepts transactions." Moonbeam's own news page has no separate post on the shutdown; its latest entries are the two July announcements.
What GLMR is for now
The project site calls the new product "An AI agent settlement network on Base" and marks it "Pre-launch · Base." The site says agents find each other, agree terms and settle onchain. Jobs are held in escrow, graded by bonded evaluators, and paid out once the work is proven. The site's summary rule: "The work arrives, or the money comes back."
The whitepaper (Version 1.0, dated September 2026) says jobs follow the ERC-8183 lifecycle, with Moonbeam's logic added through that standard's hook. The seller locks a deposit larger than the job, the buyer pays a small premium, and "Coverage pools funded in GLMR stand behind the seller's deposit." The verdict is "computed from sealed evidence rather than issued by a party the participants must trust."
On the token's role, the site says GLMR will stand "behind guaranteed agent work, and earning a share of the premiums buyers pay" once "assurance opens". It also says governance "is defined with the community before it opens." No launch date has been published.
What ERC-8183 is
ERC-8183 ("Agentic Commerce") is a draft Ethereum standard, created on 25 February 2026. A job holds escrowed funds and moves from Open to Funded to Submitted. It then ends as Completed, Rejected or Expired. On completion the provider is paid; otherwise the client gets the money back. The evaluator is one address set when the job is created, and it is the only party that can complete or reject submitted work. Optional hook contracts can add checks before and after most actions, but they cannot block the refund after expiry. Because the standard is still a draft, details may change.
Where does your GLMR stand after the Base move?
Answer a few questions about where you held GLMR to see what the article says applies to you.
Where did you hold your tokens before the 31 July 2026 deadline?
- On a custodial platform → The platform was meant to handle it
- In my own wallet on the Moonbeam parachain → next question
- I already hold GLMR as an ERC-20 on Base → Check the contract address
- I hold MOVR on Moonriver, not GLMR → The same move applied to MOVR
Did you bridge through the migrator portal at migrate.portal.moonbeam.network before 31 July 2026?
- Yes, I bridged → Check the contract address
- No, I did not bridge → next question
Was any of that GLMR deployed in Moonbeam DeFi, such as liquidity positions, lending markets or staking contracts?
- Yes, some was in DeFi → DeFi funds may be inaccessible
- No, it sat in my wallet → No published procedure after the deadline
Moonbeam told holders on custodial platforms that no action was needed and that the platform would handle the migration. Check the platform's own notices for the date and method it used.
The live token is the ERC-20 GLMR on Base, at 1:1 with parachain GLMR. Compare your token's contract address with the one in Moonbeam's 3 July 2026 announcement, and do not trust addresses posted in replies or direct messages.
Moonbeam's news page gives no procedure for self-custody holders who did not bridge by 31 July 2026. Treat anyone offering a late migration service with suspicion and look only for an official Moonbeam update.
Moonbeam said positions had to be withdrawn from Moonbeam DeFi before bridging, and warned that funds left in on-chain protocols may become inaccessible once the chain winds down. Look only for an official Moonbeam update.
Moonriver announced the same 1:1 migration of MOVR to an ERC-20 on Base, with no fee and a deadline of 31 July 2026. The same checks apply: confirm the token contract only from official Moonriver or Moonbeam announcements.
This follows only Moonbeam's published migration guidance and cannot check your wallet, recover tokens left on the parachain, or say what GLMR is worth.
What Moonbeam was: the Polkadot years, 2021–2026
- November 2021: Moonbeam won Polkadot's second parachain auction through a crowdloan. Moonbeam reported a final total of 35,759,931 DOT from more than 200,000 participants. The DOT was locked for a 96-week lease and returned to contributors when the lease ended.
- 17 December 2021: the lease began and Moonbeam started its three-phase launch on Polkadot.
- 11 January 2022: Moonbeam said the launch was complete, with token transfers and the EVM enabled. This allowed collator staking, project deployments and crowdloan reward payouts.
- Crowdloan rewards: the pool was raised to 150 million GLMR. The first 30% (45 million GLMR) was paid at launch, and the other 70% (105 million GLMR) vested linearly over the lease.
- Later: Moonbeam renewed with a further parachain slot that ran into June 2025.
On Polkadot, Moonbeam's selling point was Ethereum compatibility. Solidity contracts and standard Ethereum tooling could deploy with few or no changes, while the chain relied on Polkadot's shared security. GLMR paid for gas and secured the network through collator staking. The new site says plainly that "Both jobs ended with the parachain" and that "Base now provides the security GLMR used to buy."
Moonbeam was built by PureStake, a blockchain infrastructure company whose CEO was Derek Yoo.
Practical checklist for GLMR holders
- Check which GLMR you hold. The live token is the ERC-20 on Base. Compare the contract address with the one in Moonbeam's 3 July announcement, and do not trust addresses posted in replies or direct messages.
- If you held GLMR in your own wallet on the parachain and did not bridge: Moonbeam's news page gives no procedure for after the deadline. Treat anyone offering a "late migration" service with suspicion, and look only for an official Moonbeam update.
- If you held GLMR on a custodial platform: the platform was meant to handle the migration. Check its own notices for the date and method it used.
- DeFi positions left on the parachain: Moonbeam warned that these "may become inaccessible" once the chain winds down.
- MOVR holders: the same 1:1 Base migration and 31 July 2026 deadline applied.
Risks to weigh
- Pre-launch product: the AI-agent protocol has no published launch date. GLMR's stated role depends on a product that does not exist yet.
- Draft standard: ERC-8183 is still a draft, and its design may change.
- Self-reported information: most migration details come from Moonbeam's own announcements, and some parts contradict each other (the deadline wording).
The shutdown date of 1 August 2026 comes from a single third-party source, Tatum, rather than from Moonbeam itself.
